Re: P0140 trouble code remains. New sensor WTF?
Get some MAF cleaner from autoparts store and clean the MAF. Your converter if stock may be going or already is bad. Try using a bottle of Chevron Techron in the next couple fillups. I sued the Techron in a 96' Camry with 220k miles on it that was throwing a P0420 'Bad Cat' and Bad O2 sensor codes. After 2 fillups with the Techron with Shell gas, the Check engine lights went away and so did the codes. Techron is the only additive proven to actually clean these compnents in a vehicle! Trust me, I know Exon/Mobil Engineers that use this stuff in their test engines to keep data fair and accurate!
